TO ALL WHOM I'I MAY CONCERN: v

- Be it known that I, H. O. AMES, of New Orleans, Orleans parish, andState of Louisiana, have invented certain new and useful Improvements inRotary Steam Pumps; and do' hereby declare that the following is 'afull, clear', and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

The present invention consists of a buck 4t-wheel arranged to lrevolvewithin a suitable casing, to which 'steam is admitted in any proper'manner to act upon the buckets composing the wheel, and then exhaustedor allowed to escape therefrom, in combination with a spiral screw-bladeo r shaft connected with and operated byV the said bucket-wheel, whichscrew-blade is arranged to turn in the way or 'passage for the water,which, by its revolution, is thus drawn through such passage or way witha force and speed proportionate tov that Withwhich the bucket-wheel isrevolved by the action of the steam and the gearing connecting itwiththe spiral screw= blade. In the accompanying plate of drawings, myimprovements in rotary steam pumps are illustratedl Figure is anelevation of one side of the pump-Casin g, with portions broken out toshow the interior con= struction and arrangement of the pump.

A, inthe drawings, represents a wheel, secured to a horizontalcent-regshaft, B, arranged to'turn in bearings of the sides G, of anupright'casing or'boxD, in which the s-aid wheel turn steam-tight. Thiswheel,around its periphery, is provided with `a series of buckets, E, atequal distances apart, to each of which, in regular order' andsuccession, as the wheel revolves, steam is admitted through the steamvpassage F, communicating with the casing D at or near its top. The steamthus admitted actingupon thesidesof the said buckets, revolves the wheelof which they form a'part, and then escaping through the exhaust portGr, at the lower `portion vof the casing D, enters the water-passage orway H. Around the periphery of the wheel A, to oneside of its bucks ets,a gear-ring or wheel I is secured, with which interlocks or engages thetoothed or gear-wheel J, arranged to turn, by its horizontal shaft K, insuitable bearings of the water-way or passage H, hiereinbeforereferredto: This gear-wheel J has openings L through it and upon each side ofthe same; a similar spiral or screw-shaped blade, M, is secured to'andaround itsgshaft K, the extreme diameterof which blades is equal ornearly so t6 the internal diameter ot' the water-way H. The shaft of thegear-wheelJ is arranged sothat it can be moved in its bearing tothrowitsrA gear into or out of gear with the bucket-wheel vgear I, toaccomplish which I use a. lever-handle that is hung on a fulcrum in thewater-way H, projecting outside of 'the same at one end, and at litsother or forked or clutch .end O, interlocking with an annulargroove orrecess, l?, made in the spiral or screw-blade shaft K. From theabove-described arrangement of the gear-wheel or screw-blade shaft K,and its connection with the lever-clutch O, it is plainly obvious thatby moving the handle end of thesaid lever ir. the proper direction thegear-wheel J can be either thrown out of or brought into connection withthe bucketIl wheel gear, as the case may be; the said gear J, when inconnection with theVbucket-wheel, revolving in conjunction with it, andthus its vscrew-blades drawing and forcing the. water through thewater-way or passage H with a velocity and force indirect proportion tothat with -which the bucket-wheel is revolved by the action of the steamadmitted to it and the intermediate .gearing employed between it and theblade-shaft. In the use of myimproved rotary-pump, a water pipe orhose-suitable for conducting the water to and from the pump is firstconnected to the ends of the water=passage or way, when the screw-gearbeing thrown into connection with the bucket-'wheel gear, by properlymoving the lever-handle therefor, and steam being admitted to thebucket-wheel, the said wheel is-revolved, and consequentlyAthe'screw-blade shaft thereby drawing and forcing the water through thewater-passage or way H with a force proportionate to the force exertedupon the bucket-wheel by the steam, and the arrangement of intermediategearing, as hereinbefore stated,the steam escaping from the wheel-casingthroughthe opening G, hereinbefore referredto, into the water-passage orway, where it condenses and mixesl vwith the water passing through suchway. B y the arrangement and combination of the bucket-wheel andscrew-blade shaft or propeller, for forcingV the water through thewater-passage, it is plainly apparent that more than one screw-bladeshaft, each revolvingin a suitable and vseparate water-way or tube, maybe connected with oneand the same bucket-wheehthus increasing'thee'ective power and working of .the pump'.` In lieu of arranging therevolving screw-blade outside of the budget-Wheel7 it may' be arrangedso as to revolve in a position concentric therewith o1' at the centre ofthe bucket-wheel, the operation then being substantially the same, butthis arrangement is not advisable when more than one water-Way is tovbeemployed or used in connection with one and the saine bueket-Wl1eeL Idov not claim broadly the steam-wheel or the screw or propeller-.bladeby themselves or separately, as I am fully aware that they have bothbeen separately used before, but

What I claim as new, and desire to secure by Letters Patent, is

The steam-wheel A, and screw or propellerblade M, combined together -andarranged and operating sub` stantially in the manner and for the purposedescribed.

The above specification of my invention signed by me this 29th day ofJune, 1866l H. 0. AMES'.
